The decentralized and individualized mining in the past no longer exists, and the concentration of computing power has become the trend of the mining industry, and has entered the era of large mining farms. The cloud mining market for C-end users has gradually become a hot spot. On the one hand, the C-end is large, and cryptocurrency investment users are developing rapidly. On the other hand, high-quality mining projects are springing up. Cloud mining platforms are becoming a linker and converter for C-end users and blockchain investments.   At present, some cloud mining platforms such as Bit Deer, Bit Fufu, and OHhash have appeared in the market, which have the characteristics of integrating upstream and downstream resources and obvious profitability. It is worth noting that Ohhash integrates blockchain governance, DAO, NFT, etc. To the mining track, the future is worth looking forward to.   To sum up, as the mining difficulty increases, the mining threshold will only get higher and higher. It is foreseeable that cloud mining is likely to become the best choice for small miners to mine in the future. Therefore, the cloud mining track is an excellent track worthy of attention in recent years.   2. Definition and classification of cloud mining   The usual steps of blockchain mining are: "purchase mining machine - deploy mining machine - set up mining - obtain income", but this step of deploying mining machine is affected by many factors, such as currency, mining machine, electricity price, site, temperature , noise, operation and maintenance, etc. These thresholds require certain conditions and knowledge to eliminate, so a sub-module under the mining industry, cloud computing power, came into being.   Cloud computing power is a remote mining mode. Users purchase cloud computing power contracts through the platform, lease computing power for mining, and obtain income regularly. The advantage of cloud computing mining is that users do not need to have an in-depth understanding of mining principles and various software and hardware, or purchase expensive mining machines, and do not need to maintain 24 hours by themselves. As long as they place an order to buy, they can participate in mining and obtain mining income. , similar to the purchase of income rights products. For ordinary investors, purchasing cloud computing power contract products (leasing computing power) is a low-cost and low-threshold mining method. Investors can regularly receive mined coins, which is more stable than buying coins. At the same time, mine owners rent out their computing power to obtain cash flow in advance and diversify risks to achieve a win-win situation.   The users brought in by cloud mining are not only helpful for the sales of mining machines, but also for the upstream and downstream mining farms in the industry, and the mining pools will help to drive the value-added of the upstream and downstream industries. If a cloud miner wants to become a participant of a mining pool, then the user needs to purchase a certain amount of "hash power." Each participant receives a proportional profit share according to the amount of rented hash power.   2.1 Classification   Currently, there are 3 known cloud mining methods, namely:   Virtual Private Server (VPS) This method of mining requires renting a server and installing mining software. In other words, rent a computer that can be accessed remotely from the internet.   Rent computing power It involves buying or obtaining a contract with a company to rent some of its computing power. Typically, users can choose to rent or lease how much computing power. Their income will be proportional to the computing power they receive.   Its biggest advantage is that you don't need mining hardware to start mining. Hence it is the most common and used cloud mining method. But be aware that due to its popularity, there are many companies that sell this computing power fraudulently.   Managed Mining In this model, the company pays the miners. That is, they are responsible for the consumption and maintenance of the client's mining hardware.   This is not a very common method because many miners cannot afford these fees, but they have the equipment, so they host it to a professional company, so they can get a good yield.   Now companies that provide bitcoin mining services have begun to "move" this cloud mining function to smartphones. Users only need to log in to the mobile APP to purchase, place an order, and pay directly through the cloud mining package. Each valid package can be managed on the mobile phone, such as viewing the daily income curve, switching mining pools, changing the income address, and continuing. Pay electricity bills, etc. In addition, these mobile APPs also have the characteristics of traceable computing power, direct payment from mining pools, transparent user income, and flexible choice of service packages. Through authentic, transparent, safe and convenient services, everyone can truly mine.   3. Status of cloud mining market (industrial status)   3.1 Development History   Cloud mining platforms have been around for almost as long as mining pools. Cloud mining has begun to rise, and the number of cloud mining products in the market is increasing. In 2013, CEX opened the world's first Bitcoin cloud mining platform, and the user scale grew rapidly. Bitfury, a Russian mining machine manufacturer, acquired CEX in 2013. Benefiting from Bitfury's mining farm resources, CEX's cloud mining business developed further. accelerate. Subsequently, Swedish mining machine manufacturer KNC launched the cloud mining product KNC Cloud, relying on the 7PH/s computing power of its northern Swedish mine, and gradually took the lead in the field of cloud mining business. Unlike CEX, KNC and other cloud mining companies that have mining resources as their development support, China's domestic Huobi.com develops cloud mining business by cooperating with other mining farms, and its cloud mining platform Digcoin builds large-scale mining operations. Machine clusters, overall management of power supply, in-depth promotion of cloud mining business.   Up to now, the mining industry has a complete ecological chain, and cloud mining companies are gradually entering the C-end market, which heralds the advent of the era of large mining farms and the end of the era of personal mining.   3.2 Market size   According to Brandessence Market Research, the cryptocurrency mining market will reach $2,285.4 million by 2021. The cryptocurrency mining market is growing at a strong CAGR of 28.5% and will reach $5,293.9 million by the end of 2028. The huge demand for cryptocurrencies is one of the major factors driving the growth of the global cryptocurrency mining market.   At the same time, the global "cloud mining service market" is growing rapidly. Through the data analysis of Genesis Mining, BitFufu, BitFawn, Nicehash, Hashnest, OHhash and other companies, the situation is as follows:   Compared with 2021, by 2028, the global cloud mining service market size is expected to reach tens of billions of dollars, and the compound annual growth rate during 2022-2028 is unexpected.     3.3 Industry positioning   In fact, cloud mining is the linker and converter of the B-side and C-side of the blockchain. Compared with investors buying their own mining machines for mining, cloud computing mining and mining machine rental mining are more convenient and worry-free, which are mainly reflected in the choice of currency, purchase of mining machines, investment amount, transportation, custody, maintenance, etc. There is a professional team to deal with it, and users do not need to endure loud noises, and do not need to worry about hidden dangers.   At the same time, with the popularity of cryptocurrencies in the world, more and more users are pouring into this industry, and mining may become the first investment in the industry. Compared with other projects, mining coins generally have a cost price, which makes it easier for users to generate trust. At the same time, the cost of obtaining coins will be lower than the market, which is the preferred target of most conservative investors. the majority in the world.

  In addition, nearly 85% of bitcoins have been mined. The old coins no longer have advantages, and the mining pool computing resources are relatively concentrated. Small mining farms no longer have the advantage of competing for blocks. Instead, the new coins are future trends.   4.Cloud mining market demand and pain points   4.1 Mining demand drives the development of cloud mining   The era of huge profits in mining has passed. The core competitiveness of large mining industry and commerce is two: 1. Power resources; 2. Large-scale and professional maintenance level. In short, cost advantage and technical advantage. For large mining industry and commerce, relying on these two advantages to earn stable and reasonable profits is the demand for stable operation, so large mining industry and commerce are also willing to rent out their computing power in the era of non-profiteering mining, while for ordinary users , invest funds to share mining dividends and profits, and the two parties are connected, so the cloud computing power market is formed. The risk of speculating on coins (short-term trading to earn the price difference) is higher than that of coins (long-term bullishness). Cloud computing power brings a small amount of mining income to investors every day, and it is also controlling investors' "frequent operations" in disguise. The market opportunity of cloud mining is that it provides individuals with a more "neutral" investment method. The threshold is lower than that of self-built mines, the risk is lower than short-term operations, and the cost is lower than market price purchases; it also allows mines to share costs and risks. Get better cash flow.   Compared with self-purchased mining machine mining, cloud mining has the following advantages:

1. Cloud mining does not require large-scale purchase of mining machines in the early stage, the financial burden is light, and the threshold is low.

2. Cloud mining has high stability and does not need to bear additional risks such as mining machine failure and performance loss.

3. Cloud mining does not require investment in post-maintenance costs

The in and out of cloud mining is flexible, and the risk of lock-up is minimized compared to mining mach

It is precisely because cloud mining has many of the above advantages and market demands that cloud mining has gradually become a highly sought after darling in the market.  

4.2 The Pain Points of Cloud Mining   There are currently three major pain points in the cloud mining market, mainly in three aspects: the opaque mining of cloud computing power, the lack of liquidity of cloud computing power, and the low utilization rate of cloud computing power funds.   The opacity of cloud computing mining is due to the fact that individual users buy the computing power of centralized miners. How users know the real computing power of the miners and the actual computing power of the purchased shares can only depend on the Miners' trust. This will lead to the opacity of subsequent computing power gains, which may cause losses to participants.   If the revenue is not transparent, it is only a partial loss of revenue. A more serious problem is that the mining machine and computing power cannot be redeemed after the user pays, which will lead to greater personal losses. In addition, most ordinary users' understanding of cloud computing power is not necessarily very accurate, and may be misled by concepts. For example, it will confuse Filcoin's cloud space and effective storage computing power. Users may buy "cloud space" instead of generating income. "Effective Storage Computing Power". This will also cause losses to users.   The reason for the lack of liquidity of cloud computing power is that the current "cloud computing power" is often purchased from a certain miner. If users have turnover needs, it is difficult to transfer, and often they can only be transferred under the same miner's banner, and the operation The process is cumbersome, and cross-miner transfers are almost impossible.   The utilization rate of cloud computing power funds is not high, because after buying the "cloud computing power" shares, users can only wait for mining income, and can no longer use their assets to participate in other financial activities, and their capital utilization rate is not high.   5. Comparison of cloud mining projects and operation modes   For the business model of cloud mining, make a vertical comparison with different platform types of cloud mining, and make a horizontal comparison on different mining methods. Horizontal comparison：

  Vertical comparison：

  Mainstream platform comparison： Project Introduction   BitDeer：BitDeer opens the form of mining machine grouping, starting from one set, all investors can place orders on the platform with one click to enjoy cloud hosting services.

NiceHash also exists as an important system network. By providing support for the creation of new coins, providing transaction verification and transaction services for daily mining, NiceHash has become an important role in the cryptocurrency world.  

6.Cloud mining investment income   6.1Mining fees of different cloud computing products   In this chapter, Sirius Labs will analyze the cost and return on investment of various types of cloud computing mining.   After considering some risks, cloud computing mining has a certain cost advantage over buying coins. Especially when the currency price skyrockets, this cost advantage is particularly obvious. Because the cloud computing power contract is a standardized contract product, the price has a certain stability. The pricing of contract products will not be quickly adjusted in time with currency price fluctuations. This creates a low-risk arbitrage opportunity: continue to obtain BTC at a low price in the future through the cloud computing power contract, and sell it in advance at the current price higher than the current estimated cost in the contract exchange to profit. Since cloud computing power mining can lower the threshold for users to obtain digital currency, which is more cost-effective than buying coins directly on exchanges? ►Graph Mining cost  

6.2 Mining calculation cost Some of the factors that affect the return on investment in cloud mining. The most obvious is cost (which is why cloud companies are rated on price). The service charge includes electricity, storage and equipment charges. On the other hand, the decisive factor is the reputation and reliability of the company, since fraudulent schemes and bankruptcies prevail, then the profits do not exist. Profitability calculators (eg, Genesis modules) typically perform calculations based on electricity bills, an initial investment in hardware. In effect, it's a combination of ongoing costs and a one-time investment.   In the case of personal mining, the ongoing cost is to pay the electricity bill, and the monthly mining fee can be entered in lieu of the electricity bill. This cost can be calculated as a monthly operating cost by multiplying the unit of electricity consumption and a conversion factor of 0.744 (energy per kWh in units per kWh) multiplied by a conversion factor of 0.744. However, for cloud computing fees, a different calculation is required, as the provider provides an (effective) monthly running cost. Therefore, users need to calculate the equivalent cost per kWh of cloud mining to input into the mining calculator. This is done by dividing the monthly running cost by a conversion factor of 0.744.   6.3 Mining cost of cloud computing products VS buying coins   In addition, since cloud computing power mining can lower the threshold for users to obtain digital currency, which is more cost-effective than buying coins directly on exchanges?   ►Graph: Mining cost of BitDeerffiVeryHash  

  7. The future development direction of cloud mining projects   Cloud mining products are emerging continuously. Mining is no longer a game for retail investors and non-professional miners. Cloud computing power is just the best way to realize that everyone can mine, and mining tends to be standardized. In the era of everyone mining, standardization and specialization are the general trend.   The business model of cloud computing power mining is progressive, but the current cloud computing power mining machine service platforms on the market generally have the problem of investment asset protection risks and weak services. Many organizations looking at the prospects of cloud computing services are also actively improving these problems.   The cloud computing power mining platform is bound to tend to a healthy and healthy development. Transparent industry standards and standardized operation systems can be achieved through decentralization; cooperation with high-quality mining farms and high-quality services throughout the whole process will become the core competitiveness of the platform to seize the market.   The future cloud mining platform has the following characteristics:   decentralization   The stability and reliability of the platform are the primary criteria for choosing a cloud mining project, followed by profitability and flexibility. This standard will also drive cloud mining projects to have opportunities in the future to appear on a decentralized security platform. It can avoid problems such as excessive concentration of computing power.   Tokenization of computing power   The tokenization of computing power means the emergence of a computing power market. Through the blockchain method, the computing power can be traded more transparently and conveniently, allowing users to participate in mining anytime, anywhere. At the same time, the features of general availability and appreciation will benefit the holders more, and will also turn the holders of tokens into mining users, achieving a real quantum leap. At present, there is no similar platform.   Combine with NFT:   Cloud mining platforms are currently at the edge of the blockchain field. In order to truly enter the mainstream, on the one hand, the industry does not have a high degree of user recognition of mining attributes, and on the other hand, the community atmosphere is insufficient. The platform can combine mainstream gameplay such as NFT to increase the recognition and stickiness of users, which will be more conducive to the development of the industry.     Decentralized governance:   At present, the vast majority of governance platforms in the market are centralized, which leads to a single model and greatly reduces user participation. In the future, the decentralized governance method may increase the category of mining projects, increase the gameplay of the project, and show the same activity as the trading platform.   8. Investment opportunities for cloud mining projects   It can be seen that it is very difficult for individuals to participate in mining for gold. But the times are constantly developing. The most subversive spirit of blockchain lies in decentralization and breaking the monopoly of centralization. The emergence of cloud computing power has made the general public see the hope of gold nuggets, and the era of personal mining will reappear. . According to the introduction, a large number of blockchain currency holders and new users will flock to this new track, and various mining projects and mining platforms will become hot spots.   In the selection of cloud mining projects, comprehensive consideration should be given to: One is security: after all, blockchain security is the first priority, whether it is the user's personal information or the security of wallet assets, it is crucial;   The second is the interaction of operations: because cloud computing power mining involves mining machine computing power, mining farm management, mining pool data, wallet transfers, on-chain deposits and withdrawals, etc., these data are closely related; The third is product scalability: in all cycles, the cloud computing power product is a product that changes according to market changes. The price of mining machines is changing, the daily output of currency is changing, the currency price is changing, and the exchange rate is changing. Therefore, the scalability of the software is very important, which means whether you can make timely adjustments according to market changes, and be flexible in principle.   In terms of cloud mining platforms, the following characteristics are more attractive for investment:   1.Rich upstream and downstream resources, with physical mines as a guarantee; 2.The team has many years of experience in mining and blockchain projects; 3.The team has strong innovation ability and can quickly launch new gameplay; 4.Users can participate in governance and identify and launch various new projects; 5.Possess pass-through gameplay to ensure maximum user interests;   Although there are various opinions on the popular cloud mining companies, there is no doubt that the following companies play an important role in the mining ecosystem and have high investment value.

  COVID-19 has had an unprecedented impact on the global economy, and amid the pandemic, cryptocurrencies have had a positive demand shock across all regions. The global cryptocurrency market is expected to grow from $1.44 billion in 2020 to $1.63 billion in 2021, at a compound annual growth rate (CAGR) of 12.9% (ReportLinker, 2021). Grayscale's 2021 Bitcoin Investor Study (Grayscale, 2021) shows continued growth in interest, awareness and acceptance of Bitcoin and the entire digital currency ecosystem. Specifically, the percentage of people willing or considering investing in bitcoin products rose from 36% in 2019 to 59% in 2021.   Increased investor interest in the cryptocurrency market is also reflected in trading volumes. Coinbase, the world's largest cryptocurrency exchange, achieved rapid revenue growth due to a surge in trading volume. According to the annual report data (Coinbase, 2021), Coinbase's operating income in 2019-2020 increased from US$534 million to US$1.3 billion, a year-on-year increase of 139.14%; the net profit turned losses into profits, and the net profit before tax in 2020 was 409 million Dollar. Coinbase Q3 2021 net income was $1.2 billion, more than four times of what was achieved a year ago. However, that figure was down from more than $2 billion in the second quarter. Coinbase (2021) reported that Bitcoin accounted for 19% of transaction volume and Ether accounted for 22%. The remaining 59% came from other crypto assets, which were up from 50% in the second quarter.   In the short term, under the influence of the epidemic in 2020, the decline in economic stability and the introduction of quantitative easing policies by central banks in various countries will increase the market's demand for risk aversion and value preservation, driving the price and transaction volume of digital cryptocurrencies led by Bitcoin to rise rapidly. At present, the global epidemic continues, superimposed on the previously announced $1.9 trillion Economic Relief Bill and $2.3 trillion Infrastructure Plan announced by the US government, the market expects global inflation to rise, providing momentum for the continued cryptocurrency boom.   In addition to purchasing cryptocurrencies and cryptocurrency-related products, investors can also acquire cryptocurrencies from their roots for a long period of time through mining. Mining refers to the acquisition of cryptocurrencies by performing proof of work or other similar computer algorithms. The consensus mechanism is used to verify and confirm transactions on the blockchain, preventing fraudulent transactions or modifications. Because mining is not a labor-intensive industry, theoretically, mining can be done as long as there are mining machines and electricity available.   This is the investment method favored by many companies. According to incomplete statistics, as of February 19, 2021, 17 listed companies disclosed that they have purchased Bitcoin mining machines, and 10 of them have disclosed the power of mining machines (close to 21EH/s), including Bitfarms, Marathon Patent Group, Digihost Technology, MGT Capital Investment, etc. In 2020, due to the skyrocketing price of Bitcoin, coupled with the continuing epidemic and chip shortages, the supply of mining machines will be in short supply. In the market, first-hand mining machines have been sold out, and second-hand mining machines are at a large premium. From this point of view, mining has also become one of the popular ways to invest in the cryptocurrency market in 2020-2021.   This report will first explain the factors that affect miners’ paper profit as a basis, further analyze the miners’ earnings of mainstream digital currencies and new digital currencies in 2020-2021, how investors are now entering the mining investment market, and finally, introduce mining investment in 2022 Mine potential project.  

Factors Affecting Miners' paper profit

  According to the data of glassnode, the daily income (fees + block incentives) of miners this year is almost around 1000BTC. As of the date of this report, being December 14, 2021, the daily revenue of Bitcoin mining was $44.65M, a year-on-year increase of 129.64% compared to the previous year (Ycharts, 2021). The mining of cryptocurrencies has extremely high demands on computing power and energy consumption. Therefore, there are currently small-scale miners in the mining industry who are unable to make profits, and gradually withdraw from the existing incentive system. However, due to the high valuation of cryptocurrencies, a large number of industrial miners with higher computing power and capital-intensive operations continue to profit.   This report divides miners’ income into two categories and conducts a funnel-type analysis. The first is the Book Income of miners, which is only affected by the amount of coins mined by miners and the price of coins. The second is the Net Income of mining, which needs to be further considered. There are also relevant cost factors such as electricity, equipment prices, etc. The correlation between the two can be expressed by the formula:   Mining Income – Mining Cost = Mining Net Profit   The paper profit of miners is directly determined by the amount of mined currency and the price of price-corresponding currency. According to the specific rules of cryptocurrency, the amount of currency is directly related to the computing power that miners can provide, but is not the only relevant factor. Take Bitcoin as an example, the Bitcoin block production speed is constant at one block every ten minutes, and the difficulty of mining changes with the computing power of the entire network (that is, the more computing power available, the more the difficulty of mining will increase accordingly). Therefore, the main factor affecting the number of miners is the ratio of the computing power held by itself to the power of the entire network. The proportion can also be understood as saying that the miner has a higher probability of winning in the competition for online accounting rights. Secondly, the amount of rewards in cryptocurrencies also has corresponding quantitative rules, so the overall correlation can be sorted into the following formula:  

In addition to the above factors, the net income of miners also needs to consider cost-related factors, the most important of which is the cost of electricity, that is, the price of electricity, as well as equipment costs, site costs, costs of mining machine and power consumption of the mining machine . The mining of cryptocurrencies requires the output of a large amount of electricity, and the price of electricity is the variable cost that needs to be considered most. The world's total electricity consumption is about 154,620TWh. The average annual electricity consumption of Bitcoin mining is about 188TWh, which is 0.12% of the global electricity consumption, and even exceeds the annual electricity consumption of some countries (Ssaurel, 2021). The electricity consumption of Ethereum mining is 44.46TWh per year (Beekhuizen, 2021), accounting for about 0.03% of global electricity consumption. Therefore, the consumption of electricity is huge. In addition, the price of the mining machine itself is also a fixed cost that miners cannot ignore. The number of miners and their own computing power also determines the size of their computing power. In general, after excluding the non-direct core cost factors such as site and labor costs. the overall relationship can be integrated as:   Unit electricity price * number of miners * power consumption of miners = variable cost Variable cost + mining machine price * number of mining machines (i.e. fixed cost) = mining cost   The above is a direct relational expression of miners' income-related factors, and how each factor is affected requires further analysis. For example, the price of cryptocurrencies, the difference between cryptocurrencies and fiat currencies circulating in various countries is that they are not controlled by any national government or central bank, so their prices will not be directly determined by any individual. An article published by Coinario in 2021 analyzes that the price of cryptocurrencies is generally affected by five factors: supply and demand, production costs, competitiveness, regulatory regimes, and the scale of adoption. Therefore, paper profit of miners will also be affected by various aspects of the macro and micro environment.  

Miners’ Reward Trend Of The Old and Emerging Crypto Currencies During 2020 to 2021

2.1 Bitcoin

Bitcoin is one of the most popular and dominant crypto currencies in the world. Because of Bitcoin’s limited number of tokens (the Bitcoin protocol is capped at 21 million), inflation is avoided when it comes to this cryptocurrency.   Its “anti-inflation” ability was further strengthened at the end of 2020, and the price has repeatedly hit new highs. It broke through the $50,000 mark in early 2021, and reached $66,000 in April this year (Messari, 2021).   The rise in the currency price is good news for miners who have a large reserve of mining machines in the early stage, because it makes the investment return cycle shorter, while the mining machine merchants increase the price accordingly at the same time. Investors who purchase mining machines during the period of rising currency prices will increase their mining costs, and their corresponding net reward will be lower than that of miners who carried reserves in the early stage.   If the floating indicators such as currency prices are not taken into consideration here, it is noted that from January 2020 to November 2021, the daily reward per hash rate unit of the cryptocurrency Bitcoin indicated in a downward trend, according to the data shown as below.

Graph 1： Bitcoin reward per hash rate unit VS. Cumulative reward curve Notes： 1.Daily reward per hash rate unit = Daily mining reward / Daily total hash rate;2.Source: OKeX;3.Bitcoin’s reward unit is: BTC/TH

On May 18, 2021, the People's Bank of China issued the "Announcement of China Internet Finance Association, China Banking Association, and China Payment and Clearing Association on Preventing the Risk in Virtual Currency Transactions" through its official WeChat account.   Afterwards, an announcement was made to ban mining-related businesses in China and enforced a temporary suspension of Bitcoin mining operations in China, which accounted for more than 75% of global bitcoin mining activity at that time. The Cambridge Bitcoin Power Consumption Index (University of Cambridge, n.d.) shows that Bitcoin mining power consumption in China was zero in July.   The suspension of Bitcoin mining operations in China may be one of the potential reasons why Bitcoin’s network-wide hashrate dropped sharply from late May to early July, This also corresponds to the phenomenon that Bitcoin’s mining daily reward per hashrate unit has a small step-by-step callback from May to July.   It is precisely because of China's repression on Bitcoin mining, the shutdown of farms, and the decline in the computing power of the entire Bitcoin network that the mining difficulty has also been reduced accordingly, so the enthusiasm of overseas miners has greatly increased.   As of December 2021, the latest computing power of the entire network has recovered to 188.9 EH/s, and the daily unit hashrate reward of Bitcoin mining is 0.0000056 BTC/hash.  

2.2 Ethereum

Unlike Bitcoin, which tends to function as a payment and store of value, another giant of cryptocurrencies, Ethereum, is a distributed blockchain computing platform for smart contracts and decentralized applications. Users can issue smart contracts and digital currencies on their platform, and “gas” needs to be burned for transactions on the Ethereum platform. Therefore, in addition to mining Ethereum as income, miners can also earn fees by packaging transactions on the chain.   The daily reward per hashrate unit of Ethereum mining has a general downward trend from 2020 to 2021. After a slight increase in the daily reward in July this year, it dropped again. As with Bitcoin’s uptrend, the underlying reason for Ethereum’s modest July uptick was a small drop in hashrate due to the temporary suspension of Chinese mining operations.

2.3 Chia

Chia, which just launched last year and was founded by BitTorrent founder Bram Cohen, adopts the Proof of Space and Time to secure the network and verify transactions. The feature of Chia is that it uses the spare space of hard disk to verify the blockchain, reduces the extra cost of mining machines and power consumption, and prevents the waste of resources (Hands, 2021), which is more suitable for ordinary users to participate in. A survey by Hands (2021) shows that Chia consumes 500 times less electricity than Bitcoin and 200 times less than Ethereum. A spokesperson from Chia said in November that the Team is developing a data-sharing prototype for the World Bank's Climate Warehouse, which is described as a "non-exclusive, open-source and free solution for the public good," reflecting Chia's commitment to pursuit of green blockchain.   Due to the ease of operation of Chia mining, the daily unit hash income on the Chia Mainnet reaches 0.0774 XCH/TiB. As a large number of miners poured into Chia's mining market, computing power rapidly increased and daily unit computing power income dropped significantly by 22 times to 0.00349 XCH/TiB in just 3 months. As of November 2021, Chia's daily unit hash income is 0.00025 XCH/TiB, and the unit hash income at the initial stage of the Mainnet launch is more than 300 times that of the current one.

Arweave is a network created by combining multiple blockchain technologies, trying to connect those who have storage space with those who need permanent storage, so as to achieve a decentralized, censorship-resistant way to permanently store data. Arweave's PoA (Proof-of-Access) mechanism is generated on the basis of PoW (Proof-of-Work), which solves the problem that PoW requires all nodes to synchronize all blocks to verify the entire data. As the legitimacy of the chain will lead to the expansion of the data scale on the chain over time, it will limit the number of full nodes to a certain extent, and reduce the degree of decentralization and access performance, and other shortcomings. The consensus mechanism of PoA allows miners to start mining without synchronizing the entire chain and only needs to download some blocks, which lowers the mining threshold. The selection of the recall block is based on the hash value and height of the previous block, and if you want to mine a new block, you need to have a recall block for verification. Therefore, the game rules of mining have changed from the previous mechanism of Bitcoin and Chia coin, which simply relies on computing power or storage space to get rewards and distribution:   Probability of mining block reward = probability of having historical data x probability of being the first to solve the hash value   Therefore, when miners have more storage space for storing past blocks on the chain, they will increase the probability of mining new blocks and getting rewards. In addition, the mechanism of PoA will incentivize miners to store rare blocks, not just those that have been copied perfectly. In this way, the miners who stored the rare block will compete with fewer miners for the same level of rewards in the PoW mechanism. At present, the project has upgraded the PoA mechanism to SPoRA (Succinct Proofs of Random Access), and the purpose of this upgrade is to prevent miners from storing data in cloud servers such as AWS and Google Cloud in order to increase the probability of having historical blocks. In this way, miners are encouraged to use local hardware to store data to prevent the centralization of storage resources.   The following picture shows the price trend of AR coin since 2020. It was found that its price had been in the doldrums throughout 2020 without major fluctuation, but since the beginning of 2021, the overall price has shown an upward trend with great fluctuation. In the second half of this year, it was in a relatively high and volatile state. It reached a staged peak in November, and then fell rapidly. As of the date of this report, the price is in a state of recovery. This shows that even in the case of a decrease in unit hash income, the actual income of miners will change significantly due to the fluctuation of transaction price.

2.5 BTC, ETH, CHIA-- Monthly Sum of Mining unit Hashrate Daily Average Income

Chart 5: 2020-2021 BTC, ETH, CHIA Monthly Sum of Mining unit Hashrate Daily Average Income.

  The above picture shows the monthly total trend chart of the daily unit Hashrate or storage space income of BTC, ETH and XCH, in which the Hashrate unit of Bitcoin is calculated in TH, the Hashrate unit of Ethereum is MH calculation, Chia coin Calculated in TiB of storage space. Because Tether is the dominant trading pair in the central exchange, the following revenue calculations are unified in USDT as the final unit.   As the above figure shows, the unit income of Bitcoin has fluctuated. From the beginning of 2020 to October 2020, it showed a steady decline as a whole, from about 4.56 USDT per unit of computing power to about 2.26 USDT, and then began to slow down. in April 2021, it reached a staged high, nearly 9.20 USDT. Since then, it has been in a state of high volatility, and its income has again recently dropped to around 4.0 USDT by the end of this year. In contrast, the unit computing power of Ethereum has little fluctuation with the relatively flat trend and slow rising. But as of the date of this report, there has been a significant decline this month, from the total of 2.22 USDT in November 2020 to 0.92 USDT.   The Chia coin has been online for a short period of time, and the corresponding US dollar price has not been released since May 4, 2021, so the Chia image above is short. Chia's unit storage space income dropped significantly at first, from around 47.12 USDT in the first month to around 5.76 USDT, and then fell further. As of the date of extracting the information in this report, the latest revenue per unit of storage space in November 2021 dropped to around 1.15 USDT. According to the data analysis of Chia’s price and the number of coins that can be obtained per unit of storage space, it has been found that the downward trend is caused by the sharp decline of both. The starting price of Chia coin in May 2021 was $670.44, and it climbed to a maximum of $1551.25 during the month. Thereafter, it began to fall continuously, and the average daily price in June dropped to $458.96. Recently, the price dropped to around $138. The number of Chia coins that can be obtained per unit of storage space has also dropped from the initial 0.0043XCH to the currently maintained price (around 0.00025XCH).  

How Investors Enter the Mining Investment Market

  With Bitcoin and Ethereum both launched for more than 5 years, there is still an opportunity for investors to join the mainstream cryptocurrency mining market. This report uses the indicator "Hash Rate Difficulty/Coin Price" to judge the profitability of mining. If the increase in the price of the currency far exceeds the increase in the difficulty of the computing power, it means that there is still room for profit in mining. From the following two figures, it is not difficult to see that the “Hash Rate Difficulty/Coin Price” indicators of Bitcoin and Ethereum have been on a downward curve since May 2020, indicating that mining profits are considerable and beneficial to miners.

  If you join the mining market now, you may encounter the two problems of prolonged payback period and insufficient computing power of a single miner to obtain block rewards. The extension of the payback period is caused by the premium of miners brought by the rise in currency prices and the increase in the cost of new miners. Bitmain’s Antminer S19 Pro, which was reportedly sold at an official price of $1,897 in November last year, was still completely sold out after doubling the price; at present, the same machine is priced at $3,769, a 98% markup (Le & Huang, 2021) , The price of the same machine in the second-hand market once reached $7,999, an increase of 321%. Under the situation of rapid and linear cost growth, the return period for investors will be extended accordingly. In addition, Bitcoin and Ethereum, as mainstream cryptocurrencies, have an exponential increase in the computing power base of the entire network in the mining market, and the computing speed of a single mining machine or a small number of devices on this basis is not as good as large mining machine owners, which makes it less likely for such miners to receive block rewards. New cryptocurrencies will also encounter the same problem. As the popularity of the coin increases, more miners will be attracted to the mining market, the computing power of the entire network will increase, and the mining difficulty will also increase accordingly, thus making the probability of miners getting block rewards decrease. In response to these two problems, solutions have also appeared in the market in a timely manner, and were provided to different types of investors.   If the investor is a professional who has studied computer equipment, he or she can join the mining pool after purchasing the mining machine to increase the probability of obtaining block rewards. The mining pool is a website established by combining computing power, and the combined computing power of the mining pool can calculate the correct answer faster and obtain block rewards. Under this mechanism, regardless of the computing power possessed by individual miners, as long as they participate in mining activities by accessing the mining pool, they can obtain a small amount of token rewards by contributing to the mining pool. This is the cooperative mode of multi-person cooperative mining, and the rewards are shared according to the level of individual contribution. In this way, individual miners can improve the stability of their miner earnings. In addition to the mining market of mainstream cryptocurrencies, participating in the mining of hot projects can also reap big rewards in the short and medium term. According to the formula: daily mining unit computing power income = daily mining reward/total computing power, in the ideal mode, if the total computing power of the entire network is at the minimum value and the total revenue is at the maximum value, the daily unit computing power profit will be maximized. The first batch mining is in line with this characteristic. The “first batch mining period” refers to the period when the mainnet of the token is completed or shortly after the completion. Because it takes a great deal of time and senior technical support to prepare the mining machine and test in the early stage, the computing power of the entire network during the first mining period will be at a relatively low stage. At the time, the popularity of the token was not too high in the initial stage of the mainnet launch, and the number of miners involved in mining was not large. On the other hand, in order to attract more miners to join in order to maintain the security of the network, the number of block output rewards in the initial 1-3 years of the launch is at the highest level in the overall plan (the specific halving time depends on the specific cryptocurrency). For example, the block output reward of Bitcoin for the first four years is 50BTC/block, and the reward will be halved every four years. Chia, which will be launched on the mainnet in 2021, is the most intuitive example. The unit computing power income of 0.07745XCH/TiB in the initial stage of the mainnet launch is more than 300 times the unit computing power income in November. Miners who have researched computer equipment and networks can look for potential projects in the early stage, and obtain returns in the short to medium term through the mining income of the first mining period.   If investors do not know much about computer equipment, the computing power platform lowers the threshold for such investors to enter the mining investment market. The computing power platform sells mining as a service, and investors can participate in mining by renting cloud computing power instead of directly buying or renting mining machines. Such services are also known as cloud mining services. In this mode, investors do not need to purchase expensive mining machines, select mining farms, calculate electricity costs and other costs, and also don’t need to operate and maintain a full-time service.24 hours a day. After the contract ends, if investors do not want to continue purchasing cloud computing services, they do not need to worry about dealing with machines and venues. In addition, the computing power platform provides standard computing power, which means that there is no need to worry about the lack of machine performance and the need for replacement. Although cloud computing services provide non-professionals with convenient investment channels, it does not mean that all cloud computing platforms are reliable. Because the computing power platform sells virtual products, some platforms may use the profit rate as a gimmick to attract users to buy, and then trigger a runaway event. Therefore, when non-professionals purchase cloud computing power, they need to focus on the reliability of the computing power platform. For example, whether the computing power platform is supported by a physical mine, whether the income is received daily, or whether the platform supports real-time withdrawal. The cloud computing power leased by investors on the computing power platform always comes from mining machines, which makes the support of physical mining farms particularly important, because the scale and configuration of the mining farms provides a guarantee for the supply of cloud computing power. In addition, if the computing power platform provides two functions of daily income settlement and real-time withdrawal, it will increase users' trust in the platform. Users can withdraw profits in a timely manner and carry out capital turnover, which also eliminates users' worries that the profits may not be able to be withdrawn if they are stored in the platform account for a long time.  

Sirius Labs will keep exploring potential projects in 2022

Finding hot projects with great potential is the premise of participating in crypto mining as soon as possible when the mainnet is launched. In addition to the solid technology, financial support from the leading investment institutions is also a must for a potential project.   In the following paragraphs, we are going to introduce three projects invested by three top investment institutions. All of these are currently in the testnet/pre-testnet stage.  

1. Spacemesh

Spacemesh is committed to building a blockchain mesh operating system, designed to run on everyday users' home PCs, rather than dedicated cloud servers or specialized non-commodity hardware such as mining farms, thus reducing mining thresholds (Spacemesh Testnet Guide, nd). Just like Chia, Spacemesh uses time and space consensus mechanism (PoST) to replace Proof of Work (PoW), in order to avoid a lot of energy waste and mining centralization. Spacemesh received $15 million in A round, led by the leading investment institution - Polychain(Spacemesh, 2018).   2. Aleo

Aleo's goal is to develop a platform that utilizes zero-knowledge proofs (ZKPs), which are cryptographic techniques that allow two parties on the Internet, such as applications and users, without sharing the underlying information, to verify the information with each other. In today's transparent blockchain world, privacy enables the protection of users' personal data and expands the design space of applications. Howard Wu, the founder of Aleo, has worked closely with some prominent academics at Berkeley, Cornell, Hopkins, and other institutions, and published papers on Zero-Knowledge Proof Research. The Aleo team is capable of strong execution and develops the testnet of their protocol quickly, and wrote the programming language Leoy and a development environment for Aleo. Aleo raised a total of $28 million led by Andreessen Horowitz (a16z), Placeholder VC, Galaxy Digital, Variant Fund and Coinbase Ventures (Roberts, 2021). Aleo is still in the stage of preparing for the testnet.   3. Ironfish

Ironfish is another privacy-focused blockchain project that uses zero-knowledge proofs to create user-friendly private cryptocurrencies. Iron Fish is inspired by the Sapling protocol, which allows users to send transactions in a way that is completely shielded by design. The Iron Fish network is easy to use and has a simple protocol architecture, providing users with a cash-like transaction infrastructure.   The core purpose of the project is to lower the bar and make it easy for anyone with a computer to run a node. Iron Fish is led by Elena Nadolinski, a former engineer at Microsoft, Tilt, and AirBnb, who the a16z team described in an article as “a talented individual with technical expertise, passion, and leadership to succeed in this field” (Yahya et.al, 2021). Iron Fish has secured $27.6 million in Series A funding led by A16z (Castillo, 2021).
